Gordon Murray, creator of the McLaren F1, originally conceived the car purely as a road vehicle. Following the launch of the F1, teams competing in the newly established BPR Global GT Series — which featured racing-modified sports cars such as the Ferrari F40 and Porsche 911 Turbo — identified the McLaren as a potential class leader. After persuasion from Le Mans winner John Nielsen and team principals including Ray Bellm and Thomas Bscher, Murray relented and agreed to produce a motorsport variant.
An unused F1 chassis destined to become chassis 019 was taken as the development prototype. Given how closely the road car's engineering already approached racing standards, the conversion required less modification than might be expected. Aerodynamic work added cooling ducts at the nose and sides, a large adjustable fixed rear wing, and replaced the standard brakes with carbon units. The interior was stripped and fitted with a full roll cage. The standard gearbox, central seating position, and butterfly doors were all retained. Because of the prevailing regulations, the BMW S70/2 V12 required an air restrictor that reduced output to around 600 PS, making the racing car less powerful than the road-going original yet faster overall due to significant weight reduction. Nine chassis were built to the original 1995 specification.
For 1996, McLaren introduced an updated specification with extended front and rear bodywork, a larger front splitter, a lighter magnesium gearbox housing, and more robust internals, reducing weight by 38 kg. Nine new 1996-spec cars were built, and two earlier cars were upgraded. The 1996 car achieved 330 km/h on the Mulsanne Straight at Le Mans, faster than its own 1997 successor and faster than the contemporary Porsche 911 GT1.
The 1997 specification represented the most radical departure. As the BPR series was absorbed into the new FIA GT Championship and purpose-built homologation specials from Porsche, Mercedes-Benz, Lotus, and Panoz arrived, McLaren was forced to undertake a comprehensive aerodynamic overhaul. A substantially longer nose and tail, wider rear wing, and widened wheel arches were developed on a purpose-built exterior while retaining the original carbon-fibre monocoque. Ground clearance was revised to 70 mm front and rear. The BMW V12 was reduced in displacement to 5,990 cc via stroke reduction to prolong engine life while maintaining power within the restrictor limit, and the standard gearbox was replaced by an X-trac 6-speed sequential unit. Ten 1997-spec cars were built. To homologate the radical new bodywork, McLaren constructed three road-legal cars using GTR 97 bodywork, known as the McLaren F1 GT.
The F1 GTR debuted at the 1995 BPR season opener at Jerez, where three cars immediately claimed the first three qualifying positions. Ray Bellm and Maurizio Sandro Sala won the opening race by 16 seconds. McLarens dominated the championship through most of the season, winning the vast majority of rounds, though they encountered occasional defeats from Porsche and Ferrari at circuits including Anderstorp and Montléry. The final four races of 1995 all went to McLaren. In 1996, with updated cars, McLaren maintained their pace until the second half of the season when Porsche's new 911 GT1 proved competitive, winning at Brands Hatch, Spa, and Zhuhai. McLaren's GTC Competition nonetheless took the teams championship in both 1995 and 1996.
With the FIA GT Championship forming for 1997 and purpose-built rivals from Mercedes-Benz, Porsche, and others arriving, McLaren developed the Long Tail 1997-spec cars. The principal backing came from BMW Motorsport operating through Schnitzer Motorsport, Team Davidoff, and Parabolica Motorsports. The McLarens opened strongly, winning the first round 1-2-3 over six trailing 911 GT1s, but Mercedes-Benz progressively overcame early reliability issues to dominate the second half of the season. BMW Motorsport finished second in the teams championship. BMW withdrew at the end of 1997 to develop its own Le Mans Prototype programme, and McLaren withdrew factory support for 1998. The remaining privateer teams could manage no better than fifth in any race during 1998, and when the GT1 class was abolished for 1999 due to Mercedes dominance, the F1 GTR's FIA GT career ended.
Team Goh purchased two 1996-spec F1 GTRs for the JGTC GT500 class in 1996, competing as Team Lark. The McLarens were immediately dominant, winning four of the six rounds — including the opening round at Suzuka with Naoki Hattori and Ralf Schumacher — and claiming the GT500 teams championship ahead of Japanese factory teams from Toyota and Nissan. Team Lark did not return in 1997 due to disputes with the GT Association over car handicap penalties.
McLarens reappeared in JGTC in 1999 with Team Take One acquiring a 1997-spec car, but the intervening improvement from Toyota, Honda, and Nissan left them struggling for competitiveness. Despite this, in 2001 the Take One McLaren achieved an unlikely outright victory at Mine Circuit, finishing nine seconds ahead of a factory Nissan Skyline GT-R. Both Take One and Hitotsuyama Racing continued campaigning F1 GTRs through 2003, with Hitotsuyama making two final appearances in 2005 — the last F1 GTR to compete anywhere in the world.
McLaren entered seven cars at Le Mans in 1995 — all chassis built at the time. The race was expected to be won by WSC-class Le Mans Prototypes, purpose-built open-cockpit racing cars that were theoretically far superior to GT1 machinery. However, numerous prototype entries encountered mechanical failures during the race, while the McLarens circulated reliably. In the closing hours, five F1 GTRs were still running against only three WSC survivors. Chassis 01R, driven by Yannick Dalmas, Masanori Sekiya, and JJ Lehto under the Kokusai Kaihatsu Racing banner, took outright victory in one of the shortest overall distances covered since the 1950s. Three more McLarens finished third, fourth, and fifth overall. To mark the result, McLaren produced five special F1 LM road cars — one for each finisher. The winning chassis was retained by McLaren and never raced again.
In 1996, McLaren entered seven cars again but could not repeat the victory, with their best placed cars finishing fourth through sixth behind three Porsche entries. In 1997, six Long Tail cars started and only two finished, claiming second and third overall behind the winning Porsche LMP. The 1998 Le Mans entry was limited to two privateer cars, one of which finished fourth.
The 1995 Le Mans victory remains the defining achievement of the F1 GTR — an ostensibly road-derived car defeating purpose-built racing prototypes at the world's most demanding endurance race. The result prompted McLaren to produce the F1 LM series of road cars as a commemorative edition and established the car's reputation as one of the most successful crossovers between road and racing machinery in motorsport history.
